The MXR pase 90 is the best sounding phaser I've played on, you can get one for $69 from musician's friend. The MXR phase 100 is probably better, though. It has the same circiutry as the 90, but it has a control for depth as well as speed (plus, Steve Vai uses one). That new Danelectro "mini" phaser sounds pretty good, just ot quite as thick as the MXR (but it's cheaper).
